Armstrong Teasdale

M&A: smaller deals, up to £50m Tier 2

Armstrong Teasdale's client roster is predominantly made up of medium sized entrepreneurial companies, both listed and privately owned. Many of the transactions undertaken by the former Kerman & Co team (which was acquired by the US firm in early 2021) are sell-side, on behalf of such businesses. A large proportion of the work has an international dimension, with the firm's membership of the Alliuris network helping it to develop key relationships when working on cross-border mandates. Peter Kohl, who leads the corporate department, has over 30 years' transactional experience. Other key names to note include Martin O’Donoghue and Una Deretic who both have significant experience acting on cross-border transactions. Yvonne Costello is also highly rated.

Armstrong Teasdale have partners and staff with a massive work ethic and ability to focus on multiple aspects of a deal at the same time.’

Una Deretic, Peter Kohl and Joan Yu for Corporate and Capital markets are people I have worked with for many years and trust 100%. The only times my deals have gone awry is when I have not taken the advice of these people!

A small team which does a very high proportion of corporate work in the sector, AIM and with resources companies. They have a keen understanding of markets.’

They are different in that each problem or transaction is looked at “in the whole” and they have a very business-like approach to issues, unlike most firms.’

He gets on very well with clients, gives clear legal advice which is given in the commercial context of his client. I have no hesitation in referring him litigation and arbitration work.’

‘Robin Pickworth: hard working, very sensible towards recommendations and costs, highly structured and impressive knowledge.’

‘I have worked closely with Robin Pickworth. We were adverse to each other in a very hostile and volatile situation. Normally I end up despising the lawyer on the other side but although he was tough as nails, he won my respect as an excellent lawyer – he is also unflappable and a pleasure to deal with.’

‘James Thorndyke is brilliant with clients and with getting a deal done. Also a good sounding board for bouncing ideas off.’

Kerman & Co is committed to being a responsible business and to ensuring that we operate in a socially conscious and an environmentally sustainable manner.

Inclusion & Diversity

Like our clients, we embrace diversity, and we employ staff from a range of educational and cultural backgrounds. Where possible, our staff work flexibly. We support The Law Society’s commitment to securing a more diverse and inclusive legal profession.

We regularly monitor diversity within the firm. The results of our most recent annual review process (based on the number of respondents) showed that 53% are female, while 32% come from ethnic minorities. We have a very broad range of employees across the age groups, 58% of which are between 25 and 44 years of age, with 10% 55 years or older.

Our employees also come from a mix of educational backgrounds, with almost 19% attending school outside the UK while 48% attended UK state schools.

We strive to create a safe and inclusive workplace for all our employees, and to broaden their skills and experience so that they can grow and prosper with us.

Community & Pro Bono

We are committed to supporting the communities where we do business. We regularly collaborate with clients, NGOs and charities to deliver pro bono services. We support a number of charities with fundraising and other activities, we regularly organise fundraising events and all our staff our encouraged to support these. We do not have an exclusive relationship with a particular charity, but have recently raised money for The Sick Children’s Trust, Coram Fields, Seeing is Believing, The British Heart Foundation, Children with Cancer and Crisis.


We are committed to reducing our impact on the environment. For many years now, we have operated (as best we can) as a paperless office – relying on IT to store and file documents. Where we do use paper, we recycle large quantities of it and use recycled materials where appropriate. We also have a follow-me print management system, which helps us to eliminate wastage due to unclaimed printing, and the software actively monitors the environmental impact of all our print devices. All our employees have access to an environmental impact dashboard that displays their personal contribution to the firm’s printing/copying output.
